RAIN-WATER FILTER.

SPECIFICATION forming part of Letters Patent No. 424,651, dated April 1, 1890.

Application filed May 28, 1889. Serial No. 312,389. (No model.)

To all whom it 12mg concern.-

Be it known that I, NATHAN II. LONG, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and usef ul Improvements in ItainWVater Filters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in rain-water filters which are adapted to be detachably secured to the side of a building and have a connection with the water-spout, and provided with a suitable valve or cut-off for regulating the flow of water from the spout through. the filter, so arranged that said filter maybe entirely disconnected from said spout when it is desired to remove the same or any part thereof.

The particular construction, arrangement, and combination of the various parts of my said invention I will now proceed to point out and describe, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of a filter embodying my invention, showing the same attached to the sides of a building and connected with the spout, dotted lines indicating the position of the branch pipe connecting the filter with the main spout when said branch pipe is disconnected from the filter. Fig. 2 is a vertical central section taken through the filter and branch pipe and spout. Fig. 3 is a detail of the lid or top of the filter removed, showing the connection between the branch pipe and interiorof the filter. Fig. 4 is a detail illustrating the means I preferably employ to secure the filter to the building.

Referring to said drawings, A represents a cylindrical chamber forming the outer casing of the filter, which, as well as the other parts of my said invention, is preferably made of sheet metal. Said chamber is provided with. a conical or funnel shaped bottom a, tcrminating in a discharge-pipe a.

a is a pipe secured to the building, into which the discharge-pipeis adapted to empty.

Said pipe a can be connected with a cistern or other suitable receptacle for the water.

The chamber A is secured in a vertical position to the side of the building. To secure the same in position, I preferably attach a bracket B to the building, having at each end projecting lugs b. To one lug is hinged a spring-band B, which surrounds the upper portion of the filter and has a hook I) on its free end, which engages with an eye b in one of the lugs I).

B is a loop secured to the bracket and extends down and around the discharge-pipe a. It will thus be seen that by unhooking the band from the eye the filter can easily be removed.

0 is an interior cylindrical chamber having a closed bottom and being of less diameter than the outer chamber or cylinder A, so as to leave a space between said chambers when the chamber 0 is placed within the chamber A. Said chamber G is also provided with lugs or feet a, which rest upon the bottom of the chamber A, raising the same so as to form a space between the bottoms of said chamhers.

D is a vertical tube secured to the center of the bottom of the chamber 0 and extending up to and slightly above the top of said chamber. Said tube is provided with perforations d, extending from its lower end about one-third of the way up said tube, and with a row of perforations (1 arranged around said tube below its upper end. The upper end of the tube is open. Around the outside of the tube and within the chamber 0 is packed a suitable filtering and purifying material E, such as charcoal or other desired substance.

0 are perforations in the upper part of the cylindrical chamber 0, through which the filtered water passes, as hereinafter described.

0 are smaller perforations at the bottom of the chamber, which permit a small amount of water to escape, but are especially adapted to free the inner chamber of water after it ceases to fiow from the conductor-pipe to prevent freezing.

F is a removable top or lid,which is placed upon the chamber A, and is provided with a central opening f, in which is removably secured a short section of pipeG, held inplace by means of a flange g. Said pipe enters the upper end of the tube D when the several .parts of the filter'are assembled.

' 1', having its bearings in the section I and being located at the entrance to the branch pipe.

t is a spring-lever on the end of the shaft 1', by means of which the cut-off or valve may be operated. When the lever and valve are in the position shown in Figs. 1 and 2, the valve is turned to discharge the water into the branch pipe. 'When in the position shown in dotted lines, the water is cut off from the branch'pipe and flows down the main spout.

The branch pipe is provided with a downwardly-projecting outer end It, on which is mounted a short telescopic section or union L, secured to said branch pipe by a link Z, arranged to permit said section or union to be moved up or down upon said end or to be turned thereon. The branch pipe is of such a length and so arranged that by turning the revoluble section I its outer end 70 can be placed directly over the pipe G, located in the lid or top of the filter. When so adjusted by moving the telescopic section down, it will enter the mouth of said pipe, thus establishing connection between the filter and main spout.

The filter having been connected with the main spout and the cut-off or valve turned to discharge the water into the same, the operation of the invention is as follows: The water entering the tube D through its connections with the branch pipe passes through the perforations in the bottom of said tube up through the filtering and purifying material, then through the perforations c in the upper part of the inner chamber 0, then down to the bottom of the outer chamber to the dischargepipe. By turning the valve in the main spout the supply of water may be regulated or entirely cut off, if so desired. The filter can easily be removed by disconnecting the telescopic section or union from the pipe G and turning the revolnble section of the spout until the branch pipe is to one side of the 'filter,.as shown in dotted lines, Fig. 1. The

top or lid of the filter is then taken off and the inner chamber removed from the outer chamber.

The several parts For this purpose I provide the chamber 0 with a bail C.

of the supporting-band from the eye in the bracket and lift the filter out of the lower loop, which engages with its discharging-pipe. It will thus be seen that the filter I have described can be easily and quickly attached to and removed from a building without interfering with the water-spout, and at the same time forms a thorough and effective filtering and purifying device for rainwater. My said invention is also very simple in its construction and can be manufactured very cheaply. I preferably make the entire filter of sheet metal.

"While I have described the filter as es= pecially adapted to be attached to a building and connected with a water-spout for the purpose of filtering rain-water, it is apparent that it can be used in various other connections for filtering and purifying water.

Having thus fully described my said inven- 'tion,what I claim as new, and desire to secure by Letters Patent, is-

1. In a rain-water filter, the combination, with the water-spout H, having the revoluble section I, provided with the valve 2', the branch pipe K, secured to and communicating with the revoluble section and having the downwardly-bent end 71;, and telescopic section of pipe L, mounted 011 said end, of the main chamber A, secured by the side of the spout and havinga discharge-opening in its bottom, the removable smaller chamber 0, arranged within the main chamber and adapted to contain a packing of filtering material and provided with the perforations O in its upper part, and a vertical tube D, secured therein and having perforations d in its lower portion, the removable lid F on the main chamber A, havingt-he central opening f, and short pipe G, mounted in said opening and communicating with the vertical tube D, and over which pipe G the end of the branch pipe is adapted to be moved and connected therewith by means of the telescopic section L, all constructed, arranged, and operating substantially as shown and described.

2. The combination, with the water-spout H, having the revoluble section I, the branch pipe K, secured to and communicating with the revoluble section and having a downwardly-bent end 70, and a telescopic section of pipe L, mounted on said end, and a valve 2', of a filter secured by the side of the spout and having an opening in its top, over which the end 713 of the branch pipe is adapted to be moved and connected therewith by means of the telescopic section, all constructed, arranged, and operating substantially as shown and described.

3. The combination, with the outer case A of the filter, of the bracket 13, adapted to be attached to a building, the downwardly-bent 100p B engaging with and supporting the bottom of the case A, the lugs Z) on said bracket, an eye 19 in one of the lugs b, and a spring"- hand B, hinged at one end to one of the lugs b and provided With a hook Z) on its free end, said band being adapted to surround the 11pper part of the case A and have its hook b engage with the eye 11 to secure said ease in place, substantially as shown and described. 1c

In testimony whereof I aifix my signature in presence of two witnesses.
